Comparison of efficacy and safety of a proposed biosimilar QL1206 with reference denosumab in patients with bone metastasis from breast cancer: A subgroup analysis of a randomized, double-blinded phase III study.
Article in Chinese journal of cancer research = Chung-kuo yen cheng yen chiu, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04550949 (A Multi-center, Randomized, Double-blind, Comparative Study to Evaluate the Clinical Efficacy and Safety of QL1206 and Xgeva® in Patients With Bone Metastases From Solid Tumors), which is not on this map.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract
Objective: To evaluate the efficacy and safety of QL1206 (a denosumab biosimilar to Xgeva®) in breast cancer patients with bone metastasis (BM) through subgroup analysis of a randomized, double-blind phase III trial (No. NCT04550949). Methods: This subgroup analysis included patients with BM from breast cancer enrolled in a phase III trial. Patients were randomized (1:1) to receive either three cycles of QL1206 or denosumab (120 mg subcutaneously every 4 weeks). Subsequently, they received 10 cycles of QL1206 (120 mg) over 40 weeks, followed by a 20-week safety follow-up. The primary endpoint was the percentage changes from baseline to week 13 in urinary N-telopeptide corrected for creatinine (uNTx/Cr). Results: The breast cancer cohort consisted of 311 patients. Vertebral involvement (66.4%) was the most prevalent BM site at enrollment, while 27.7% of patients presented with ≥3 metastatic bone lesions. At week 13, QL1206 demonstrated a median uNTx/Cr reduction of -69.9% (range: -98.1%-568.0%) Conclusions: QL1206 demonstrated similar efficacy and safety to the reference denosumab in patients with BM from breast cancer, supporting QL1206 as a new option for management of BM from breast cancer.
